How do I slow down wheel on iOS app?

Hello,

Please, help me out, I am making updates to iOS app Make Wheels, where you put in options and they are made up into a wheel and you spin the wheel (like the wheel of fortune). I need the wheel to spin gradually, and gradually stop, and I need the little columns on the sectors to interact with the pointer (gradually stoping the spin)


I have 2 subviews in container. One of them should rotate with deceleration (wheelView), another should animate synchronously to first one (arrowView). Every time when wheelView rotates on particular angle arrowView should go up and down to simulate touch with wheelView.

With the amount of details that you've provided. here's the answer that can be produced:


You need to use a dynamic, frame based animation for the rotating wheel; and calculate the heel positions based on either "time since last frame * dynami rotational speed" or something similar.
